Hi chaps. Need some help from you guys. The car seems to have developed a problem with the steering. It seems to 'stick' after ive turned the wheel. Doest matter if i am going slow or fast. This doesnt happen all the time and seems to get worse the longer i been driving it. It has plenty fluid in the tank, although it is overdue a service. Could that be the problem? Thanks in advance guys. Cameron.

Loose power steering pump drive belt? have a look in the manual, it tells you how to tighten it and the amount of free play there should be. It's happened on both my Imprezas where the steering loses assistance briefly.
